We’ll be really disappointed if Robert Pattinsonand Kristen Stewartend up being separated for the 2012 MTV Movie Awards, because they’ve shown up side-by-side for the past three years — and they’ve always given us such hilariously awkward moments!

Continuing their tradition of on-stage awkwardness, Kristen Stewart pushed Robert Pattinson away when he tried to kiss her in 2011 (after he kissed Taylor Lautner, of course.)

In 2010, Robert Pattinson and Kristen Stewart sort of made up for the previous year’s kiss-fail when they finally locked lips onstage — too bad they fumbled first! (Getty)

They may have won the golden popcorn for “Best Kiss” in 2009, but Robert Pattinson and Kristen Stewart never delivered the kiss we were all waiting for, because K-Stew pulled away at the last minute! (Getty)

We loved that Robert Pattinson joined his Water For Elephants co-star Reese Witherspoon on stage when she accepted her Generation Award in 2011, but we doubt the censors were pleased when R-Patz dropped the f-bomb! (Courtesy of MTV)

We couldn’t keep our eyes off Robert Pattinson and Kristen Stewart during the 2011 ceremony, and they couldn’t keep their hands off each other! It was an all-night PDA fest, and we loved it.
